Bookmark or Share- International Atomic Time - WikipediaInternational Atomic Time (abbreviated TAI, from its French name temps atomique international [1]) is a high-precision atomic coordinate time standard based on the notional passage of proper time on Earth's geoid. [2] . TAI is a weighted average of the time kept by over 450 atomic clocks in over 80 national laboratories worldwide. [3] .

- International Atomic Time (TAI) - timeanddate.comInternational Atomic Time (TAI) is a time scale that uses the combined output of some 400 highly precise atomic clocks. It provides the exact speed at which our clocks tick. Universal Time (UT1), also known as astronomical time, refers to the Earth's rotation. It is used to compare the pace provided by TAI with the actual length of a day on Earth.
- Atomic clock - WikipediaAn atomic clock is a clock that measures time by monitoring the resonant frequency of atoms. It is based on atoms having different energy levels. Electron states in an atom are associated with different energy levels, and in transitions between such states they interact with a very specific frequency of electromagnetic radiation.
